-Animal Crossing - Cut this one off for sure. Every time I tried playing this game, I only got two weeks in and then got bored. The NES games are the only high point. Everything else is just as good (if not better) on the DS version.
-Battalion Wars - The Gamecube version of Advance Wars, in 3-D. Play Advance Wars, then see if you want this.
-Chibi Robo - TML is right in that it has an interesting concept but I couldn't keep myself interested in it.
-Fire Emblem - Never played FE, remember?
-Phantasy Star Online - Too repetitive. Plus it ain't worth getting the online stuff.
-Beyond Good & Evil - Now I've heard really good things about this game. Like the biggest sleeper hit on the Gamecube. Definitely worth a look.
You're forgetting Ikaruga. You should have Ikaruga on here. Top-down, hard-as-hell shooter. Which kinda got me playing it for six hours straight once because I was trying to beat my personal high score. Ohhh, the insomnia...
What school do you go to and what major are you in? O_O
